I agree - Whole herring rule. Larger hook on the front can help with the spin, depending on the size of the herring. Close the mouth, put the tip through upper mandable and lower jaw about 1/4 of the way back from the tip so it stays closed, run it back around behind the eye and back out the side you started with. Good slow roller for kings if you hook the back hook by the tail on the opposite side. Quicker spin letting ithe back hook drag. Got both Kings so far this year on whole herring and 4 oz.

Quicker vertical retrieve while mooching will reduce the dogfish bite - They have a hard time swimmming straight up to get the bait. Don't let it sit too long at one place. if the doggies are in thick.

For some reason, mooching seems to produce for me longer into the day after the trollers bite is over.
